THE ex-wife of Art Shamsky claims the Mets legend gave her a sexually transmitted disease after repeatedly cheating on her with both men and women.

In a sordid lawsuit filed in Manhattan Supreme Court, Kim Shamsky says that during their 13-year marriage the famed outfielder and first baseman “engaged in acts of adultery with both men and women,” without her knowledge. His romps included “acts of ‘unprotected’ sexual and deviate sexual intercourse,” according to the suit.
